PATTERN AND PROCESS FOR IVAKNG THE SAME.

Application filed May 1, 1925.

rhis invention relates to improved patterns and procedure tor making the same.

The chief object of the invention is to provide a master match plate pattern of great accuracy and to provide a simple eiiiective method for constructing said patterns 1n a minimum period of time.

Particularly the invention is directed to the use of a plate of transparent material, such as glass, and to the placement and matching up of the pattern parts on the opposite sides of said plate to produce the required pattern.

The practice of the invention is illustrated l5 in the accompanying drawings and is briefly described below in connection therewith, it being understood, however7 that the invention is not limited to the specic procedure `or construction illustrated and described.

Ot the accompanying drawings,

Figure 1 is a plan of a match plate pattern embodying the invention;

Figure 2 is a section on line 2 2 of Figure l; and

Figure 3 is a perspective view of an article made by use of the particular pattern plate shown.

Referring to the drawings, 10 represents a plate of transparent material such as glass which may be laid over a drawing of an arrangement of the parts to be cast and the runs therefor. The halt parts ll and run formers l2 are then adhesively secured on the plate in coincidence with the arrangement on the drawing.

The plate l0 is then reversed and half parts 13 are secured thereon in coincidence with the parts l2, whereuponl the plate l0 may be used as a master match plate by the use of which cast pieces such as shown in Figure 3 can be produced.

In the practice of the invention a transparent plate of suitable size and shape is laid upon a drawing or blue print of the pattern to be formed and previously made halves of patterns including running gates are applied to the plate so that they are aligned with or coincidev with the drawing. These parts are secured on the plate in any suitable way as by the use of an adhesive.

The plate is then reversed and the other halt` parts are similarly secured to the plate by aligning them with the corresponding Serial No. 27,317.

parts visible through the plate. The parts are thus easily and quickly matched and a more accurate pattern results from which the permanent master match plate can be cast.

After the pattern has served its purpose, the parts may be removed from the trans parent plate and the latter may be reused for constructing other patterns.

Modiiications of the invention may be resorted to without departing from the spirit thereof or the scope of the appended claims.

What is claimed is:

l. That method ot making match plate patterns which comprises providing' a transparent plate, laying the plate over a drawing ot the pattern, providing half parts of the various portions ot the pattern, applying one set ot said parts to the upper side of the plate so as to coincide with the draw ing and securing them on said plate with an adhesive, and applying the other set of said half parts to said plate so as to coincide with the corresponding parts of the rst set and securing them thereon with an adhesive.

2. That method of making match plate patterns which comprises providing a transparent plate, laying'the vplate over a drawing ot' the pattern, providing haltl parts of the various portions of the pattern, apply` ing one set oi said parts to the upper side of the plate so as to coincide with the drawing and securing them on said plate, and applying the other set of said half parts to said plate so as to coincide with the corresponding parts or' the first set and securing them thereon.

3. That method ot' making pattern which comprises providing a transparent plate, applying a halt part of a pattern to one side of said plate and securing it thereon, applying' a corresponding other halt part of the pattern to the other side or' said plate by placing it thereon so as to coincide with the lirst part visible therethrough, and securing said other halt part on the plate.

4C; A pattern for the purpose described comprising a transparent plate, and corresponding halves of pattern portions adhesively secured in coinciding relation on opposite sidesot said plate.

5. A pattern for the purpose described comprising a. transparent plate, and corresponding halves of pattern portions secured in coinciding relation on opposite sides of said plate.

6. That method of making patterns Which comprises providing a transparent plate, applying a portion of the pattern to one side of the plate and securing it thereon, and

applying another portion of the pattern to the other side of the plate in complementary relation thereto by causing its edges to co- 10 incide with the corresponding edges of the first part visible therethrough and securing Said other portion on the plate.
